On 12 Nov 2014, I was invited to talk about data warehousing in the context of the lecture series on Big Data and Analytic Applications at the Technical University of Darmstadt. Here are the slides that I’ve compiled to that end. The idea was to make the students aware of the problems that data warehouses solve in real world situations.
On 25 Nov 2015, I got invited again and presented an updated version which you find here. I’ve removed the section on in-memory databases and replaced it with a few slides on how big data complements data warehouses.
